Specification of Letters Patent.

Patented Dec. 17, 1912.

Application filed May 13, 1912. Serial No. 697,012.

To all whom it may concern:

Be it known that I, DAVID CHAMBERS, a. citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Hydrocarbon-Burners, of which the following is a specification, reference being had to the accompanying drawings.

y invention relates to a class of devices employed for burning the gases generated from oils and petroleum products in furnaces and stoves.

The object of my invention is to provide a device which can be installed in the furnaces and stoves in ordinary use, and when so installed will insure a perfect combustion, also to provide a device which is practically noiseless, economical in its consumption of fuel and can be placed for operation at a very low cost. I attain these objects as well as other advantages, by the construction, combination and arrangement of parts illustrated in the accompanying drawings which form a part hereof.

Figure 1 is a sectional view of the device on the line 11 of Fig. 2. Fig. 2 is a plan view of the device as shown in Fig. 1 with the hood removed. Fig. 3 is another form of the device without a hood and with an interior auxiliary air chamber. Fig. 1 is a side view of the burner placed in a furnace shown in section. Fig. 5 is a side view of the burner in a stove shown in section on the line 55 of Fig. 6. Fig. 6 is a front view of the burner in a stove shown in section on the line 66 of Fig. 5. Fig. 7 is a front view of damper for air pipe.

Like numerals or letters refer to like parts throughout the views.

The retort A is a circular vessel having an outer wall 7 and an inner wall 8, concentrically arranged between its top 9 and bottom 10, thus forming therein an annular vaporizing chamber B between the walls 7 and 8 and a mixing chamber B in the cen ter. An integral circular rim 11 is formed in the upper surface 9 of the retort A. In the center of the top 9 and bottom 10 are vertical threaded openings 12 and 13 respectively. A threaded pipe 141 of suitable length is provided, to extend through the opening 12 and a similar pipe 15 is provided to extend through the opening 18. The chamber B has a threaded opening 16 in its top. A pipe 17 with its lower end threaded extends through the opening 16. The upper part of the pipe 17 is curved or angled so that the upper end is in a vertical position over the pipe 1 1. Surrounding the opening 12 is a series of small openings 00 through the top 9 of the retort. At one side of the retort A is a horizontal threaded opening 18. Through this opening the end of a threaded pipe 19 extends and said pipe extends in the opposite direction to a suit able source of supply containing the material from which gas is to be generated. On the opposite side of the retort is a lug 2O threaded on its interior to receive the threaded end of a rigidly secured stand 21 which supports the retort in operating position in the furnace or stove as shown in Figs. 4: and 6. The ing 20 not being an element for which claim is made, it is shown for the purpose of illustration only and is omitted in Fig. 2 but is also applicable to the form of device there illustrated.

A circular hood is provided, of form and dimensions to engage the rim 11 of the retort and cover the pipe 17. In one side of the hood G is a threaded opening 22. Through this opening extends the threaded end of a pipe 23 shown partly broken away in Fig. 1. The opposite end of the pipe 23 extends downward into the space occupied by the ash pit as in Fig. 6. In Fig. 4; the pipe 23 is extended without the furnace and has adamper 30 in its end as shown in Fig. 7. The pipe 23 may extend through an opening 31 in the top of the hood C as shown in Fig. 4. In Fig. 3 is seen an arrangement intended to accomplish a similar object but omitting the hood C. In this the pipe 23, being similar to 23, extends directly through the opening 12 in the top 9. A pipe 15 taking the place of pipe 15 extends through the central chamber B engaging the lower surface of the top 9 and thus forming an auxiliary chamber within B and around the pipe 15. The pipe 15 has an inclined opening 24 in one side. In the upper part of the wall 8 farthest opposite from the opening 24 of the pipe 15 is an opening 25. A valve 26 is placed in the supply pipe 19, see Figs. 1 and 6.

In Fig. 4 is shown a pipe 27 leading from outside the furnace to the interior of the fire box and into a vessel 28 placed below the retort. A similar arrangement of pipe and vessel may also be placed in the stove. In Fig. 1 the grate 29 is shown cemented solid.

It will now be seen that when my device is placed in a stove or furnace as illustrated in Figs. 41, 5 and 6, the valve 26 is opened to allow distillate or vapor supplying fuel to flow or be forced through the pipe 19 from a reservoir containing the same, by any suitable means, and into the retort chamber B in such quantity as may be desired for the heat which is wanted. A. small quantity of liquid inflammable material is run through the pipe 27 and into the vessel 28.. This material is ignited and heats the retort until sufiicient gas is generated therein to flow downward through the pipes 1 1 and 15 when it ignites from the flame in the vessel 28. As the gas flows downward the pipe 23 supplies a steady flow of air which passes through the openings w into the chamber B where it unites with the gas to form a combustible mixture. The lighted gas coming from the pipe 15 passes outwardly around the circumference of the retort and upward, thus creating a circular flame and producing as intense a heat as may be desired.

In the form shown in Fig. 3 the gas passes from chamber B through the opening 25 into the chamber B and thence through the opening 24 of the pipe 15 downward through it. The air passes through the pipe 23' directly into the pipe 15 where it mixes with the gas and passes out below the re tort as just described.

The air pipe may be connected with either the top or side of the hood as may be required for arrangement in the space to be occupied. While the grates are shown cemented, this is optional but it is believed a better control of the air is acquired with a closed fire-box. The courses of the currents of gas and air through the pipes and retort are clearly indicated by the direction arrows shown in the views. It will also be seen that the pipes 1a and 15 Fig. 1, can be adjusted toward each other and the pipe 14: toward the gas discharge pipe 17 all of which aids the proper mixing of gas and air in the chamber B.

While I have shown two forms, I contend that the first one described is the better one and permits the best regulation of the flow of gas and air supply.

Other arrangements of my device may be made for the purpose of manufacturing and installing it which may difier from those shown without departing from the principles of construction and arrangement which I have shown.

I contend that my device will produce heat of any reasonably desired temperature in furnace or stove, without soot or ash and can be easily regulated, while the cost of the installation and operation is most economical and satisfactory.

Having thus described my invention I claim:

1. A hydro-carbon burner, comprising a retort having a closed vaporizing chamber, a central chamber, with an opening in its top and in its bottom, and small openings in its top adjacent to the first named therein, a vertically movable pipe of suitable length placed in each of the first named openings of said central chamber, an angled pipe extending from within the upper part of said vaporizing chamber over and vertically downward toward the upper end of the pipe in the top of said central chamber, a pipe extending from within the vaporizing chamber and outward to a suitable source of fuel supply, means in said pipe to control the fuel supply, means to support said retort in horizontal position, substantially as described.

2. A hydro-carbon burner, comprising a retort having a closed vaporizing chamber, a central chamber, with an opening in its top and in its bottom, and small openings in its top adjacent to the first named therein, a vertically movable pipe of suitable length placed in each of the first named openings of said central chamber, an angled pipe extending from within the upper part of said vaporizing chamber over and vertically downward toward the upper end of the pipe in the top of said central. chamber, a pipe extending from within the vaporizing chamber and outward to a suitable source of fuel supply, means in said pipe to control the fuel supply, a hood secured on top of the retort, a pipe extending from within said hood and outward to a suitable source of air supply, means to support said retort in horizontal position, substantially as described.

lVitness my hand hereunto.
